Sarah Jessica Parker believes Carrie Bradshaw’s friendship group may have been a “literary conceit.”

Speaking to Chris Hardwick on his Nerdist podcast, the 51-year-old actress said "I used to wonder if Samantha, Charlotte and Miranda were real,” the Divorce star, revealed of her character’s best friends, famously played by Kim Cattrall, Kristin Davis and Cynthia Nixon. “That that wasn't just her column.”

“They’re such perfectly archetypal characters,” Parker, continued. “So you’re writing a column about sexual politics and observations of female/male, primarily, heterosexual relationships, so you’re picking one type. You’re saying, ‘This type is this and this,’ and then you complicate it more, like any good writer does. So I’m not entirely sure they are real.”

According to Parker, every episode in the six-season long series was just based on the events Carrie was writing about.

“What we are seeing isn’t necessarily what happened in New York City,” she concluded.
